Polar Signals MCP

Let your agent check performance data from Polar Signals MCP during a call.

Polar Signals MCP connects your AgentCalls agent to your continuous profiling projects and performance data. During a call, your agent can look up the current state of a project, answer questions about recent performance, and point a caller to the right person or next step. Your team keeps its data in Polar Signals, and the agent reads only what you allow it to reach. Connect the tool once in your settings and the agent can use it on every call and follow-up.

Hi, this is Maya from the platform team. Are we seeing any performance regressions on the checkout service today?
Agent
Let me check the Polar Signals project for checkout. One moment, Maya.
Agent
There is one regression since this morning's release, in the payment validation path. CPU time per request is up about 18 percent.
Caller
Can you send that to Daniel? He owns the release.
Agent
Done. I have sent Daniel the project link and a short summary of the regression now.

Engineering lead checks a project before a meeting

Caller
Good morning, this is Omar. I want to know if the search indexing project has any new optimization suggestions.
Agent
Good morning, Omar. I found three new suggestions in the indexing project from the last week.
Agent
The biggest one is a memory allocation hotspot in the batch writer, which could cut peak memory by about a quarter.
Caller
Thanks. Please add that to the agenda for our two o'clock review.
Agent
Added to the two o'clock agenda with the profile link attached.
